DETAILED DESCRIPTION OF THE INVENTION

Certain aspects of the invention may be found in a method and system forproviding a home cable network. Exemplary aspects of the invention maycomprise receiving by a root node network controller in a premises-basedwired network, signals that conform to one or more first communicationsprotocols, where the signals may be received from sources external tothe premises. The received signals may be bridged to conform to a secondcommunications protocol and communicated to one or more networkeddevices comprising a television set top box downstream from the rootnode device within the premises-based network, where only signalsconforming to the second communications protocol may be communicatedover the premises-based wired network. The first communications protocolsignals may, for example, comprise data over cable service interfacespecification (DOCSIS) signals, cable television signals, satellitetelevision signals, fiber-to-the-home signals, and/or digital subscriber(DSL) signals. The second communications protocol may, for example,comprise a multimedia over cable alliance (MoCA) standard, an Ethernetprotocol, or a power line communications protocol. The premises-basedwired network may, for example, comprise coaxial cables. The bridgedsignals may, for example, be communicated to one or more networkeddevices at a frequency that is independent of the one or more firstcommunications protocols. The frequency may be configured utilizing theroot node network controller.

FIG. 1A is a diagram illustrating an exemplary dwelling-based network,in accordance with an embodiment of the invention. Referring to FIG. 1A,there is shown a dwelling-based wired network 100 spanning a pluralityof rooms in the dwelling, where each one may have one or more networkeddevices. There is also shown Multimedia over Cable Alliance (MoCA)devices 101A-101D, a root node device 102, high-definition televisions(HDTVs) 103A-103D, a game console 105, an N:1 splitter 109, a personalcomputer 111, coaxial cables 107, and an input signal 110. The inputsignal 110 may be provided by a cable head-end, a fiber-to-the-homeservice, digital subscriber line (DSL) service, or a satellite signalsource, for example. The MoCA devices 101A-101D are, for example,downstream from the root node 102 in the premises-based wired network(e.g., “downstream” meaning from the root node 102 toward the leaf nodesof the premises-based wired network, and “upstream” meaning from theleaf modes of the premises-based wired network toward the root notedevice 102, or toward the head end outside of the premises). Though onlya single N:1 splitter 109 is illustrated in FIG. 1A, the network maycomprise a plurality of splitters in the home, for example alldownstream from the root node device 102.

The MoCA devices 101A-101D (or general MoCA devices) may comprisenetwork devices that enable a secure wired network utilizing the coaxialcables 107 in the dwelling wired network 100. The MoCA devices 101A-101Dmay, for example, be stand-alone apparatus or may be incorporated inother devices (e.g., televisions, PVR, STBs, PCs, network attachedstorage (NAS) devices, etc.). The MoCA devices 101A-101D may operateunder the MoCA 1.x or 2.x specification, for example, and maycommunicate signals between devices in both the 1-2 GHz frequency rangewhen operating with a cable TV signal or ˜400-900 MHz when operatingwith a satellite TV signal. In an exemplary embodiment of the invention,the MoCA devices 101A-101D may receive MoCA signals from the root nodedevice 102 in any frequency range supported by the coaxial cables 107.Other communication protocols may be utilized on the same coaxial cables107.

The root node device 102 may comprise a network controller in the wirednetwork, coordinating the wired network communications as per the MoCAstandard. The root node device 102 may comprise a device comprising aMoCA network controller system-on-chip (SoC), or may comprise a SoCitself. The root node device 102 may also comprise some wirelesscapability and as such may configure wireless network communications viaa wireless network protocol, such as 802.11x (i.e., any one or more of802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, etc.). The root node 102may receive signals from a head end, and accordingly may be operable toreceive cable, satellite, digital subscriber line (DSL), fiber optic, orother communications protocols utilized by service providers to provideservices to the dwelling.

The root node device 102 may comprise one or more bridges for convertingthe received signals to a MoCA signal, and therefore, the signalscommunicated in the dwelling-based wired network 100 may comprise MoCAsignals only, so that the root node device 102 may utilize the entirespectrum supported by the coaxial cables 107 when communicating to theMoCA devices 101A-101D, the HDTVS 103A-103D, the game console 105,and/or the PC 111. Note that in various other exemplary networks,portions of the spectrum (e.g., portions of the spectrum that aregenerally not utilized for MoCA communication) may be allocated forother uses.

In another exemplary scenario, one or more of the MoCA devices 101A-101Dmay also comprise a network controller in the wired network,coordinating the wired network communications as per the MoCA standard.For example, one of the MoCA devices 101A-101D may operate as a backupMoCA network controller. In another exemplary embodiment, one or more ofthe MoCA devices 101A-101D may be operable to provide a WLAN network.

Cable television signals, including data over cable service interfacespecification (DOCSIS) signals, may be communicated in the 50 MHz to 1GHz range, for example. The cable range generally has about 150 6-MHz TVchannels, some of which are allocated to DOCSIS, some to digitaltelevision, and some to analog television. DOCSIS based communicationmay, for example, be used to provide Internet access to the cablesubscriber.

The MoCA devices 101A-101D may be operable to provide wireless networkaccess to devices within the dwelling. Exemplary wireless networks maycomprise wireless local area networks (WLANs) that conform to an IEEE802.11 (e.g., a, b, g, n, and ac) protocol, femtocells, Bluetooth,ZigBee networks, or any other non-public networks.

Under the MoCA standard, orthogonal frequency-division multiple access(OFDMA) enables multiple nodes to simultaneously transmit PHY-frames,each utilizing only a subset of subcarriers. The network controllerpre-allocates the OFDMA subcarrier subset to nodes on a mutuallyexclusive basis, with each OFDMA PHY frame containing reservationrequests destined solely for the network controller. The requestingnodes are to synchronize their subcarriers to those of the networkcontroller, adjust their transmissions to ensure simultaneoustime-of-arrival at the network controller, and adjust the amplitude oftheir transmissions as specified by the network controller. If theseelements are met, the network controller receives a PHY frame with apayload bitstream that is demultiplexed to recover andforward-error-correction (FEC)-decode each individually transmittedreservation request.

In an exemplary embodiment of the invention, in a network architecturethat comprises a full-band D3/Video SoC, the root node device 102 may beoperable to isolate the dwelling-based wired network 100 from the streetby residing at the root node, rather than after the N:1 splitter 109. Inthis manner, only MoCA signals may be communicated over thedwelling-based wired network 100 and there are thus no interferenceissues since the root node device 102 may coordinate the frequency ofall signals being communicated over the coaxial cable 107. For example,the root node 102 may receive cable television signals, which may be inthe 50 MHz-1 GHz range, and generate MoCA IP packets and communicate theresulting signals over any frequency within the available spectrumprovided by the coaxial cables 107. This frees the entire home cablefrequency band for MoCA transmission. In other words, there may be nofrequency spectrum inside the home that is specifically set aside forcable transmission, or for any other received signals.

In a conventional dwelling-based cable system, set-top boxes are locatedafter the splitter, such as the N:1 splitter 109, so that the entirenetwork receives the input signal provided by the service provider.Thus, a large portion of available spectrum is dedicated to a particularprotocol, whether it is being used or not.

However, by converting received signals to MoCA at the root node device102, only MoCA signals are communicated within the dwelling-based wirednetwork 100, and only the root node device 102 communicates with outsideservice provider networks, such as cable TV, DOCSIS, satellite, DSL, orfiber-to-the-home networks, for example. Thus, instead of being limitedto a particular band outside of a service provider frequency band, theMoCA communications over the dwelling-based wired network 100 has accessto the entire frequency range supported by the coaxial cables 107. Thisis illustrated further with respect to FIG. 2A.

FIG. 1B is a diagram illustrating an exemplary dwelling-based network,in accordance with an embodiment of the invention. Referring to FIG. 1B,there is shown a dwelling-based wired network 120 spanning a pluralityof rooms in the dwelling, where each one may have one or more networkeddevices. There is also shown node devices 111A-111D, the root nodedevice 102, the high-definition televisions (HDTVs) 103A-103D, the gameconsole 105, a hub 119, the personal computer 111, nodes 111A-111D,network lines 117, and an input signal 110. The input signal 110 may beprovided by a cable head-end, a fiber-to-the-home service, digitalsubscriber line (DSL) service, or a satellite signal source, forexample.

The wired network 120 is an alternative embodiment to the wired network100 described with respect to FIG. 1A. Accordingly, the wired network120 may comprise an Ethernet network, with the network lines 117comprising Cat 5, 6, or 7 Ethernet cables, for example. Similarly, thehub 119 may comprise an Ethernet hub for providing a plurality of linesfor the wired network 120 from a single input line carrying the secondprotocol signal 122.

The nodes 111A-111D may comprise Ethernet nodes for receiving Ethernetpackets and bridging to appropriate signals for target devices. Forexample, the nodes 111A-111D may receive Ethernet packets and generatevideo and audio signals to be communicated to the HDTV's 103A-103D.

In another exemplary scenario, the wired network 120 may comprise apower line communications network where the network communications maybe transmitted over existing power lines in the dwelling. Accordingly,the hub 119 may be an optional component in instances where the rootnode device 102 communicates to a plurality of devices, such as thenodes 111A-111D, over the power lines.

FIG. 2A is a diagram illustrating network frequency spectra, inaccordance with an embodiment of the invention. Referring to FIG. 2A,there is shown an upper frequency spectrum showing a satellite TV bandand associated MoCA frequency band, and a lower spectrum showing acable/DOCSIS frequency band and its associated MoCA frequency band.

In a conventional dwelling-based network, the cable or satellite signalis communicated throughout the network, thereby reserving that frequencyband for these communications. However, in an exemplary embodiment ofthe invention, the service provider signal or signals, may be receivedby a MoCA root node device, such as the root node device 102 describedwith respect to FIG. 1A, and converted to MoCA signals to becommunicated over the dwelling-based wired network 100. The root nodedevice 102 may therefore only communicate satellite/cable/DOCSIS/etc.with networks/devices external to the dwelling-based wired network 100.Thus, the entire spectrum supported by the coaxial cables may beavailable to the MoCA network in the dwelling. Accordingly, the rootnode device 102 may receive cable television signals in the 900 MHzrange, for example, and may communicate the resulting MoCA signals inthe 500 MHz range if it determines that this frequency is preferred overthe 1.15-2.15 GHz range. Frequency selection may be based on the qualityof communications in a particular frequency range, which may bedetermined by a signal strength, a signal-to-noise ratio, and/or a biterror rate, for example.

In addition, the root node device 102 may enable more flexibility inMoCA devices within the dwelling. For example, if a dwelling previouslyhad cable television service and the associated MoCA devices for cabletelevision service, and the dwelling then switched to satellitetelevision, the MoCA devices would normally not be able to function,since the MoCA bands for cable and satellite are different. However, theroot node device 102 may enable the use of these MoCA devices no matterfor which type of service provider signal they were intended.

Accordingly, the root node device 102 could receive the newly subscribedsatellite signals and communicate the resulting MoCA signals over thenormal cable television MoCA channels supported by the legacy MoCAdevices, thereby enabling the user to continue to use their cableTV-specific MoCA devices despite currently being a satellite televisionsubscriber. Since the root node device 102 may determine what frequencyband is used within the dwelling-based wired network 100, the serviceprovider communications protocol signals do not affect devices withinthe dwelling.

FIG. 2B is a diagram illustrating an exemplary root node networkcontroller 200, in accordance with an embodiment of the invention.Referring to FIG. 2B, there is shown MoCA nodes 213A-213C, a N:1splitter 209, and a root node device 200 comprising a processor 201, amemory 203, bridge modules 205A-205D, and a MoCA PHY 211. The root nodedevice 200 may, for example, share any or all characteristics with theroot node device 102 discussed previously with regard to FIG. 1.

The processor 201 may be operable to control the operation of the rootnode device 200. For example, the processor 201 may configure the bridgemodules 205A-205D to receive various communications protocol signals andto generate output signals for packetization and further processing inthe MoCA PHY 211, and/or may configure MoCA channels to be utilized bythe MoCA PHY 211. In another embodiment of the invention, the processor201 may be utilized to update and/or modify programmable parametersand/or values in a plurality of components, devices, and/or processingelements. At least a portion of the programmable parameters may bestored in the memory 203. In yet another embodiment, the processor 201may implement any one or more of the bridge modules 205A-205D.

The bridge modules 205A-205D may comprise a DOCSIS bridge module 205A,cable television bridge module 205B, satellite television bridge module205C, and other protocol bridge module 205D. In an exemplary scenario,the other protocol bridge module 205D may be operable to receive opticalsignals from a fiber optic cable and convert them to electrical signalsthat may be communicated via the MoCA PHY 211. A bridge module may, forexample, extract data and/or control information from packets receivedin accordance with a first protocol utilized external to a premises, andthen load such information into packets in accordance with a secondprotocol for communication within the premises. Note that suchrepacketization may generally be bi-directional as needed.

The MoCA PHY 211 may be operable to communicate signals over coaxialcables, such as the coaxial cables 107, where the signals conform to theMoCA 1.x and/or 2.x standards, to one or more remote MoCA nodes, such asthe MoCA nodes 213A-213C. In an exemplary scenario, the MoCA PHY 211 maycommunicate MoCA signals outside of the conventional MoCA frequencyranges since the entire frequency spectrum supported by the coaxialcables may be available, due to the root node device 200 isolating otherprotocol signals from the dwelling-based network.

The MoCA PHY 211 transmissions may be PHY frames scheduled in accordancewith the Media Access Control (MAC) Layer specifications, and as suchmay comprise a PHY preamble and a PHY payload and may apply OFDMmodulation. The root node device 200 may schedule and broadcast specificstart and stop times at which transmissions from each node begin andend, and may be communicated in response to reservation requests. TheMoCA PHY 211 may be operable to communicate MoCA signals in anyfrequency band as configured by the processor 201. In an exemplaryscenario, the MoCA PHY 211 may comprise a single transceiver that isoperable to communicate over any frequency band that the coaxial cables107 may support. In another exemplary scenario, the MoCA PHY 211 maycomprise a plurality of transceivers, each operable to communicate overa particular range of the frequency spectrum, such as the cable andsatellite MoCA channels as shown in FIG. 2A.

The MoCA nodes 213A-213C may comprise generic MoCA devices, such ascable set top boxes with MoCA capability, for example, that may becontrolled by the root node device 200. In an exemplary scenario, theMoCA nodes 213A-213C may be operable to receive multimedia data via oneor more MoCA channels, as configured by the root node device 200 andgenerate output video and audio signals to be displayed by an HDTV, forexample.

In operation, the root node device 200 may direct network traffic to andfrom a particular device via any frequency range supported by thecoaxial cables in the dwelling-based wired network 100. The root nodedevice 200 may configure the communications links between all othernetwork nodes within the dwelling-based wired network 100.

In an exemplary scenario, the root node device 200 may receive a serviceprovider signal or signals and convert them to MoCA signals that may becommunicated to the MoCA nodes 213A-213C. The root node device 200 maytherefore communicate satellite/cable/DOCSIS/etc. . . . signals withnetworks/devices external to the dwelling-based wired network 100, whileexclusively communicating MoCA signals to devices within thedwelling-based wired network 100, such as the MoCA nodes 213A-213C.Therefore, since no signals received from external systems or devicesare communicated directly into the dwelling-based wired network 100, theentire spectrum provided by the coaxial cables 107 may be available toMoCA network communications (or, for example, to MoCA networkcommunications combined with other premises-based protocolcommunications independent of signals external to the premises).

Accordingly, the root node device 200 may receive cable televisionsignals in the 900 MHz range, for example, and may communicate theresulting MoCA signals in the 500 MHz range if it determines that thisfrequency is preferred over the 1.15-2.15 GHz range, normally assignedto MoCA networks incorporating cable TV signals. Frequency selection maybe based on the quality of communications in a particular frequencyrange, which may be determined by a signal strength, a signal-to-noiseratio, and/or a bit error rate, for example.

In a fiber-to-the-home example, an optical signal may be received from aservice provider via optical fibers coupled to the root node device 200.Alternatively, the optical signal may be converted to an electricalsignal before being communicated to the root node device 200. The otherbridges module 205D may convert the optical signals to electricalsignals, and process the signals for packetization and other appropriateMoCA processing by the MoCA PHY 211, before being communicated to theMoCA nodes 213A-213C via the N:1 splitter 209.

The separation of MoCA protocol signals within the dwelling-based wirednetwork 100 and other protocols on the external side of the root nodedevice 200 may result in complete frequency spectrum availability withinthe dwelling-based wired network 100. Aliasing and other interferenceproblems may thus be avoided by configuring the channel usage such thatany aliasing will not cause interference, for example.

While FIG. 2B describes cable, satellite, fiber-to-the-home, MoCA, andDOCSIS, communications protocols, any network protocol may beapplicable, where the root node device 200 has the capability tocommunicate via two or more communications protocols. The ability of thenetwork controller to communicate using two or more protocols enablesthe exclusive communication of MoCA signals within the dwelling-basedwired network 100 while still communicating via any other type ofcommunications protocol with service providers.

FIG. 2C is a diagram illustrating an exemplary network device, inaccordance with an embodiment of the invention. Referring to FIG. 2C,there is shown a root node device 200 and a MoCA node 213D comprising aprocessor 201A, a memory 203A, a WLAN module 205A and a MoCA PHY 211A.The processor 201A, the memory 203A, and the MoCA PHY 211A may besubstantially similar to the processor 201, the memory 203, and the MoCAPHY 211 described with respect to FIG. 2A, but located within the MoCAnode 213D. The MoCA node 213D may, for example, share any or allcharacteristics with the MoCA Nodes 213A-213C discussed previously withregard to FIG. 2B.

The MoCA node 213D may comprise a networked device such as a MoCAbridge, a set-top box, a personal computer, or a gaming device, and maybe controlled (at least in part) by the root node network controllerwith MoCA SoC 200. For example, the root node network controller withMoCA SoC 200 may configure the channel frequency to be utilized incommunication of data between the root node network controller with MoCASoC 200 and the MoCA node 213D.

By separating MoCA protocol signals from the other communicationsprotocol signals at the root node device 200, i.e., communicating withsources external to the dwelling in the appropriate protocol, butexclusively communicating MoCA signals within the dwelling, moreflexibility may be obtained for MoCA devices within the dwelling. Thisis described further with respect to FIG. 2D.

FIG. 2D is a diagram illustrating an exemplary premises-based wirednetwork with multiple-service provider capability, in accordance with anembodiment of the invention. Referring to FIG. 2D, there is shown theroot node device 200 and source 1-N compliant devices 221A-221D. Thereis also shown a plurality of input signals, source 1-N, which maycomprise signals provided by a plurality of different service providers.For example, source 1 may be provided by a cable television head end,source 2 may be provided by a satellite dish mounted to the dwelling,source 3 may comprise a DSL signal provided by a telecom provider, andsource N may comprise an optical signal from a fiber-to-the-homeprovider.

The root node device 200 may be operable to receive source signals froma plurality of providers delivered in compliance with variouscommunications protocols and may then bridge the signals to one or moredesired MoCA channels as required by the receiving devices. The rootnode device 200 may therefore support the use of a plurality of MoCAdevices irrespective of the communication protocol for which the deviceswere designed.

For example, if a dwelling previously had cable television service andassociated MoCA devices for cable television service, such as the source1 compliant device 221A, and the dwelling then switched to satellitetelevision and purchased or rented the source 2 compliant device 221B,the source 1 compliant device 221A would not normally be able tofunction, since the MoCA bands for cable and satellite are different.However, the root node device 200 may enable the use of source 1compliant device 221A no matter which type of service provider signalthey were intended for, because the root node device 200 may configurethe MoCA signals at any frequency supported by the coaxial cables.Accordingly, the root node device 200 could receive the newly subscribedsatellite signals and communicate the resulting MoCA signals over thenormal cable television MoCA channels to the source 1 compliant device221A, thereby enabling the user to continue to use their cableTV-specific MoCA devices despite currently being a satellite televisionsubscriber. Since the root node device 200 may determine what frequencyband or bands are used within the dwelling-based wired network 100, theservice provider communications protocol signals do not affect deviceswithin the dwelling.

The root node device 200 may be operable to determine in which MoCAchannels the source 1-N compliant devices 221A-221D are intended tooperate, and provide MoCA signals in the appropriate frequency range foreach device. For example, if the source 1 compliant device 221A is acable television compliant device and the source 2 compliant device 221Bis a satellite television compliant device, the root node device 200 maycommunicate ˜1-2 GHz signals to the source 1 compliant device 221A and˜400-900 MHz signals to the source 2 compliant device 221B.

Similarly, the root node device 200 may communicate over any frequencyrange a source 1-N compliant device 221A-221D may operate that issupported by the coaxial cables in the dwelling-based wired network 100.Furthermore, the root node 200 may be operable to configure at whichspecific channel within the normal MoCA frequency range of the source1-N compliant devices signals will be communicated. In this manner,interference of signals due to aliasing may be avoided.

FIG. 3 is a block diagram illustrating exemplary steps in providing ahome cable network, in accordance with an embodiment of the invention.The exemplary method illustrated in FIG. 3 may, for example, share anyor all functional aspects discussed previously with regard to FIGS.1A-2C. Referring to FIG. 3, after start step 301, in step 303, the rootnode network controller with MoCA SoC 200 may receive input signals froman external source such as a head end for example. The head end maycomprise cable TV, satellite TV, DOCSIS, and/or fiber-to-the-homesignals, for example.

In step 305, the root node network controller with MoCA SoC 200 maybridge the received signals to MoCA signals. Step 305 may, for exampleand without limitation, share any or all functional aspects discussedpreviously (e.g., with regard to FIGS. 1A-2C).

In step 307, the root node network controller with MoCA SoC 200 mayconfigure the channel over which the MoCA signals are to be communicatedvia the coaxial cables 107. For example, the root node networkcontroller with MoCA SoC 200 may configure MoCA signals to becommunicated over a frequency range conventionally reserved for MoCAsignals in a cable television system, despite being another type ofsignal, such as satellite television. Since only MoCA signals may, forexample, be communicated over the coaxial cables 107, the input signaldoes not affect what frequency need be utilized.

In step 309, the MoCA data may be communicated to the receiving MoCAdevices 213A-213D, followed by end step, or the process may loop back tostep 303 if further communications are to occur.

FIG. 4 is a block diagram illustrating exemplary steps in providing ahome cable network, in accordance with an embodiment of the invention.The exemplary method illustrated in FIG. 4 may, for example, share anyor all functional aspects discussed previously with regard to FIGS.1A-3. Referring to FIG. 4, after start step 401, in step 403, the rootnode network controller with MoCA SoC 200 may receive signals comprisinga non-MoCA protocol. The received signals may be cable TV, satellite TV,telecom (DSL), or optical (fiber-to-the-home), for example.

In step 405, the root node network controller with MoCA SoC 200 maybridge the received signals to MoCA protocol signals and configure adesired channel to communicate MoCA signals over the coaxial cables 107.Step 405 may, for example and without limitation, share any or allfunctional aspects discussed previously (e.g., with regard to FIGS.1A-3).

In step 407, the receiving node or nodes, the MoCA nodes 213A-213D mayreceive the MoCA signals from the root node network controller with MoCASoC 200. The MoCA signals may be communicated in any frequency supportedby the coaxial cables 107 and the MoCA nodes 213A-213D, notwithstandingthe signals received by the root node network controller with MoCA SoC200 being intended for another protocol or frequency range not supportedby the MoCA nodes 213A-213D.

In step 409, the MoCA nodes 213A-213D may communicate an acknowledgementor communicate other desired information back to the root node networkcontroller with MoCA SoC 200 for communication to the head end, such asin DOCSIS communication, for example, followed by end step, or theprocess may loop back to step 403 if further communications are tooccur.

In an embodiment of the invention, a method and system may comprisereceiving by a root node device 102, 200 in a premises-based wirednetwork 100, signals that conform to one or more first communicationsprotocols, where the signals may be received from sources external tothe premises. The received signals may be bridged to conform to a secondcommunications protocol and communicated to one or more networkeddevices (e.g., one or more of network devices 101A-101D, 103A-103D, 105,111, 213A-213D) comprising a television set top box downstream from theroot node device within the premises-based wired network 100, where onlysignals conforming to the second communications protocol may becommunicated over the premises-based wired network 100.

The first communications protocol signals may comprise data over cableservice interface specification (DOCSIS) signals, cable televisionsignals, satellite television signals, fiber-to-the-home signals, and/ordigital subscriber (DSL) signals. The second communications protocol maycomprise a multimedia over cable alliance (MoCA) standard, an Ethernetprotocol, or a power line communications protocol.
